METER.

ToaZZjwho-m 1 t may concern Be it known that I, ALBERT B. Ryrmsnr, a

I citizen of the United States, and a resident of New York city, in thecounty of New York and State of New York, have invented a new and usefulImprovement in Meters, of which the following is a spec1- fication.

My invention relates to meters, and particularly to those instrumentswhich may be adapted to operate either as integrating meters or asindicating meters.

' The object of my invention is to provide an attachment or auxiliarydevice for an integrating meter by means of which the instrument may betransformedfinto an indicating meter. 7

My iri/ven tion is especially applicable to portable watthour meters ofthe rotating standard type, whereby the instrument, when provided with adevice embodying my invention, may be made to operate asan indicatingwattmeter.

F or a better understanding of the nature, the scope and thecharacteristic features of my invention, reference is had to thefollowip g'description and the accompanying drawi..gs in which- Figure 1is a plan view of a portion of a meter equipped with a device containingan embodiment of my invention; Fig. 2 is a J sectional side view takenon the line AB of Fig. 1, and Fig. 3 is a similar sectional side view,showing my device in an operating posltion, whereby the instrument istransformed into an indi ating meter.

Referring to the drawings, a device 1, constructed in accordance with myinvention, is mounted upon a glass plate 2 surmounting the operatingmechanism of a rotating standard type wa-tthour meter which comprises anindicator 3, supported upon "a rotatablymountedmeter shaft 4, and a dial5. The axis of the meter-shaft 4 is in alinement with the axis of acentral shaft 6 having a square cross section. The'shaft 6 pro]ectsthrough an opening 7 in theplate 2 in such manner as to be non-i-otatable.

At the lower extremity of the shaft 6 1s secured, by means bf the setscrew 8, an annular bushing 9 to'whieh is attached the iner end .of atensional element or spiral spring 10.; The outer end of the sprlng 10terminates'in a reversely curved portion or hook 11 by means of which,when the device Specification of Letters Patent.

its normal position, and in Fig. 3 a ,view

when the spring is operatively engaged with the pin 12 and the indicator3.

To transform the integrating meter, wherein the indicator 3 is revolvingabout the axis of the shaft 4 and registering the time integral of thepower, into an indicating meter. wherein the instantaneousvalue of thepower may be determined, pressure is exerted upon a button 13 which isscrewed to the upper extremity of the shaft 6. This causes the spring 10to descend to a position where the hook 11 may engage the pin 12 whenthe said pin is in a position upon the dial where such engagement can beeifected. The indicator 0 will revolve until the torsional momentoffered to it by the spring 10 is equal and opposite to the impellingmoment 0cca sioned by the armature of the internal mechj anism of themeteigwhich is not shown. The

WVhen the pressure on the button 13 is relieved, the spring 10 will bereturned to its normal position by means of a compressed helical spring14 which is positioned between the under surface of the button 13 and aface plate 15. This releases the pin 12 from engagement with the spring10, and the instrument may operate now as an integrating meter. In orderto limit the downward movement of the spring 10, the shaft 6 is providedwith a'shoulder 16 which prevents further downward movement of thespring after the shoulder has come into con tact with the face plate 15.

The shaft 6 slidingly passes through a threaded bushing 17 which is heldin the opening 7 in the glass plate 4 by means of clamping plates 18and19. These plates are screwed upon the bushing with the glass plate 4and a felt washer 20 held intermediately. Disposed between the faceplate 15 and the clamping plate 18 is a felt Washer 21 which is firmlyheld by screws 22. The purpose of the felt washers is to afiordmeclianical protection to the glass plate 2 and to exclude dust from themechanism.

The structural details may, of course, be varied from what I have shownand described within the scope of the appended claims.

I claim as my invention:

1. In an electrical measuring instrument comprising a rotating standardhaving an indicator secured thereto, a 'tensional element .normallypositioned out of engagement with the indicator, and means for effectingengagement between the indicator and the ten sional element.

2. In an electrical measuring instrument comprising a rotating standardhaving an indicator secured thereto, a tensional element normallypositioned out of engagement with'the indicator, and manually operatedmeans for efl'ecting engagement between the tensional element andthe-indicator.

3. In an electrical-measuring instrument,

the combination'with a rotating indicator,

of a tensional element surmounting the indicator, and'nieans formovingthe tensional element perpendicularly to the plane of rotation ofthe said indicator to operatively 6. In an electrical measuringinstrument comprising a rotating standard, an indicator secured thereto,a movable shaft, a spring normally positioned with one end secured tothe movable shaft and the other end unengaged, and means for moving thesaid shaft, whereby engagement may be efiected between the indicator andthe unengaged end of the spring.

7. In an electrical measuring instrument, the combination with arotatable member, of a resiliently mounted non-rotatable member, aresilient member attached to said nonrotatable member and adapted toengage said rotatable member when the non-rotatable member is depressed.

8. In an electrical measuring instrument, the combination with arotatable member, of a non-rotatable member, a spiral spring attached'to saidnon-rotatable member for engaging said rotatable memberwhen the nonrotatable member-is depressed.

9. In an electrical measuring instrument, the combination with anintegrating meter, of a tensional member, and means for operativelyconnecting said tensional member to said integrating meter to constitutean indicating meter.

10. In an electrical measuring instrument, the combination withanintegrating meter, of a tensional member, and manually operated meansfor operatively connecting said tensional member to said integratingmeter to constitute an indicating meter.

In testimony whereof,'I have hereunto subscribed my. name this 19th dayof February 1913.
